Filed June 25, 1934 2 Sheets-Sheet 2 I I INVENT R RA. WLll aIns Patented May 5, 1936 UNITED STATES PATENT OFFICE 6 Claims.

This invention relates to the cotton industry, and particularly to the float roll construction for cotton seed .delinting machines, being a continnation in part of my copending application for 5 patent, Serial No. 708,384, filed January 26, 1934.

The principal object of the present invention is to provide a float roll having fingers on the agitating bars which project between the saws and which are so shaped and capable of such adjustment relative to the saws that either practically all the lint or fiber may be removed from the cotton seed at the expense of high quality due to the seeds themselves being abraded and chipped by the saws and the discoloring particles thereof added to the lint; or a lesser but cleaner and higher grade quantity of the product may be obtained from which all particles of seed are absent.

A further object of the invention is to produce a simple andinexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views:

Figure 1 is a fragmentary front View of a delinting machine showing my improved float roll in section and mounted in connection therewith.

Figure 2 is a transverse section on the line 22 of Figure 1.

Referring now more particularly to the characters of reference on the drawings, the machine comprises a saw supporting cylinder l on which is mounted a row of circular saws 2 held in spaced relation by separator rings 3. Fixed ribs 4 are disposed between the saws, the upper ends of said ribs projecting above the saws back of the vertical center line of the saw cylinder as usual.

Mounted above and in front of said vertical center line is the float roll which includes a driven shaft 5 mounted as usual in the end plates 6 which are secured for vertical adjustment to the main frames 1 of the machine by any suitable means such as bolts 8. Fixed on the shaft 5 are longitudinally spaced spiders 9 each of which is provided with a plurality of frame brackets l projecting outwardly and radially relative to the shaft. The shaft and the saw cylinder are driven by any suitable means in opposite directions in the usual manner. So far the general construction and arrangement of the parts is substantially standard in de-linting machines.

The brackets l0 form supports for plates ll disposed parallel to the shaft 5 and secured to the brackets by bolts l2. These plates are formed along their outer edges with fingers l3 which project between the adjacent saws in clearance relation thereto. These fingers are of special form, tapering in width from the base toward their outer ends as plainly shown. By means of this shape of the fingers and the fact that the float roll as a whole may be adjusted toward or from the saws, it will be seen that when the float roll is set at the closest position relative to the saws, the space between any saw at its periphery and the adjacent edges of the adjacent fingers will be relatively small. With this positioning of the float roll, which is the position shown in the drawings, the space for the passage of the seed past the fingers and saws is reduced to a minimum. This results in the seed being held from escape until all the lint has been removed therefrom, but with possibility of the seed being scufied or cut into by the saws. In this case the particles removed from the saws become mixed with the lint itself and reduce the quality of the product correspondingly.

As the float roll is adjusted outwardly or away from the saws however the space between the saws and the fingers is increased as will be evident. With such a setting of the float roll there is more space for the ready escape of the seeds, so that while less lint may possibly be removed therefrom before they pass the fingers and are clear of the saws, there is little likelihood of the seeds being scuffed or abraded so as to contaminate the lint and the condition or grade of the latter is higher.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

1. A cotton seed de-linting machine comprising the combination with spaced de-linting saws of a float roll, such float roll comprising a driven shaft, brackets mounted on the shaft and extending radially therefrom, plates mounted on the brackets and extending parallel with the shaft and transversely of the saw edges, fingers on the plates projecting between the saws in clearance relation to the faces of the saws, such fingers tapering in width from their bases to their outer ends, and means to vary the extent of projection of the fingers between the same and hence vary the distance between the edges of the fingers and the saw edges.

2. A cotton seed-delinting machine comprising the combination with spaced de-linting saws, of a float roll, such float roll comprising a driven shaft, brackets mounted on the shaft and extending radially therefrom, plates mounted on the brackets and extending parallel with the shaft and transversely of the saw edges, fingers on the plates projecting between the saws in clearance relation to the faces of the saws, such fingers tapering in width from the bases to their outer ends, the base of each finger on each plate" being immediately contiguous to the base of an adjacent finger on the same plate, and means to vary the extent of projection of the teeth between the saws and hence vary the distance between the edges of the fingers and the saw edges. 3. A cottonseed de-linting machine comprising the combination with spaced de-linting saws of a float roll, such float roll comprising a driven shaft, brackets mounted on the'shaft and extending radially therefrom, plates mounted on the brackets and extending parallel with the shaft and transversely of the saw edges, fingers on the plates projecting between the saws in clearance relation to the faces of the saws, such fingerstapering in width from their bases to their'outer ends, and means to adjust the float roll relative to the saws whereby to move the plates to vary the extent'of projection of the teethbetween the saws and hence vary the distance between the edges of the fingers and the saw edges.

'4. A cotton seed de-linting machine comprising the combination with spaced de-linting saws, of a float roll, such floatroll including a shaft, plates' supported fronrand' extending parallel to the shaft and projecting radially outwardly therefrom, the outer edges of the plates normally extending closely adjacent to and transversely of the saw edges, fingers along the outer edge of the plates, the fingers projecting between the saw blades, the side edges of each finger converging from its point of entry between the saws toward its outer end, means to vary the depth to which the fingers project between the saws, the distance between the edges of the fingers and the saw edges when the fingers are projected to substantially their greatest depth being such as to crowd the cotton seeds closely between the edges of the fingers and the saw edges, and such crowding action being lessened when the depth of projection of the fingers between the saws is diminished.

5. A cotton seed delinting machine comprising the combination with the spaced de-linting saws and the fioat roll of the machine of a plurality of fingers associated with the roll and projecting between the saws, the side edges of the fingers converging from their point of entry between the saws to their outer ends whereby to form substantially V-shaped slots between the fingers into which the saws project, the perimeters of the saws normally lying closely adjacent the bottom of such slots so that seeds of cotton engaged by the saws must be dragged through the slots while crowded closely between the saw edges and the bottom and side edges of the slots.

6. A cotton seed delinting machine comprising the combination with the spaced de-linting saws and the float roll of the machine of a plurality of fingers associated with the roll and projecting between the saws, the side edges of the fingers converging from their point of entry between the saws to their outer ends whereby to form,

substantially V-shaped slots between the fingers into which the saws project, the perimeters of the saws normally lying closely adjacent the bottom of such slots so that seeds of cotton engaged by the saws must be dragged through the slots while crowded closely between the saw edges and the bottom and side edges of the slots, and means to adjust the relative distance between the perimeters of the saws and the bot tom and sides of said slots whereby to control the degree of crowding of the seeds therethrough.
